Given: f(x)= x^{2 }+ 7x + 12

and

g(x)= x^{2 }+ 8x + 16

Find:

1.(f+g)(x)

2.(f-g)(x)

3.(f•g)(x)

4.(f/g)(x)

#1**+3 **

1.(f+g)(x) = This is fairly simple, all you do is add the two problems.

x^{2} + 7x + 12 + x^{2 }+ 8x + 16

**2x ^{2}+15x+28**

2.(f-g)(x) = Same thing here, just subtract the two equations.

x^{2} + 7x + 12 - x^{2 }+ 8x + 16

**-x-4**

3.(f•g)(x) =

**x ^{4}+15x^{3}+84x^{2}+208x+192**

4.(f/g)(x) =

**x+3/x+4**

This is all combining like terms and simplifing. I highly recommend you use **www.mathway.com** to help you.

Hope this helps! Have a great day!!!
